Infection Reveals a Modification of SIRT2 Critical for Chromatin Association

Abstract : Graphical Abstract Highlights d Infection induces modification of the host deacetylase SIRT2 to target it to chromatin d Dephosphorylation of serine 25 on SIRT2 controls its subcellular localization d PPM1A and PPM1B form a nuclear complex to dephosphorylate serine 25 d The phosphorylation state of serine 25 is crucial for Listeria infection (P.C.), melanie.hamon@pasteur.fr (M.A.H.) In Brief Sirtuins are enzymes critical for various processes, including genomic stability, metabolism, and aging. Through study of Listeria monocytogenes, a bacterial pathogen that exploits SIRT2 for productive infection, Pereira et al. uncover a SIRT2 modification necessary for chromatin association and function.
